Tsuki isn't alone when she helps Ka, Fu, Den and Nichi out of a giant rat pack spot.
With her is one of her closest friends: Ten of the Azure Dragon of the Heavens Empire.
She's supposed to be looking for a floating mountain where the Empire's vast and terrific Guardian - the Azure Heavens Dragon - is meant to sleep; but has decided to help her Lunar friend in her quest for Calm.
Only, it's not going too well as an unsuspecting Nichi finds out:
It's all too much for Ka (people aren't supposed to live on the Sun or the Moon, never mind a vast kingdom above the clouds):
Plus makes Fu wonder how many other people are looking for 'Immortal Beings' that don't want to be found.
Although Den might have a partial answer to that question...
